I saw something very similar only when the game was running at a very low frame rate.
Yeah, I encountered this the moment I tried jumping on level 1, the game runs ridiculously slow (~5 FPS) on my old Windows 8, I don't know what's causing the low framerate as the game isn't using much of my PC's resources.
Hey, what's your GPU by curiousity? There is a large Probe Lights texture that might be causing some vram bandwidth issues.
